这篇文章主要介绍了PHP读取CURL模拟登录时生成Cookie文件的方法,包括了curl的使用及cookie的操作,非常具有实用价值,需要的朋友可以参考下

本文实例讲述了PHP读取CURL模拟登录时生成Cookie文件的方法。分享给大家供大家参考。具体实现方法如下:

在使用PHP中的CURL模拟登录时会保存一个Cookie文件,例如下面的代码

代码如下:

$login_url = 'XXX';  
  
$post_fields['email'] = 'XXXX';  
$post_fields['password'] = 'XXXX';  
$post_fields['origURL'] = 'XXX';  
$post_fields['domain'] = 'xxx.com';  
//cookie文件存放在网站根目录的temp文件夹下  
$cookie_file = tempnam('./temp','cookie');  
  
$ch = curl_init($login_url);  
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 5.1; zh-CN; rv:1.9.1.5) Gecko/20091102 Firefox/3.5.5');  
curl_setopt($ch, CURLOPT_HEADER, 0);  
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);  
curl_setopt($ch, CURLOPT_MAXREDIRS, 1);  
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);  
curl_setopt($ch, CURLOPT_AUTOREFERER, 1);  
curl_setopt($ch, CURLOPT_POST, 1);  
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_fields);  
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file);  
curl_exec($ch);  
curl_close($ch);  
  
//带上cookie文件,访问需要访问的页面  
$send_url='xxx.com';  
$ch = curl_init($send_url);  
curl_setopt($ch, CURLOPT_HEADER, 0);  
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);  
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file);  
$contents = curl_exec($ch);  
curl_close($ch);  
  
//清理cookie文件  
unlink($cookie_file);  
  
//输出网页内容  
print_r($contents);
Copy after login

在temp文件夹下保存一个cookie前缀的临时文件,例如:coo3A98.tmp文件
打开这个文件得到如下代码:

要使用php来格式化该文件,使用以下代码就能实现

代码如下:

<?php   
$cookie_folder = dirname(__FILE__)."/temp";  
$lines = file($cookie_folder.&#39;/coo3A98.tmp&#39;);  
  
$trows = &#39;&#39;;  
  
foreach($lines as $line) {  
    if($line[0] != &#39;#&#39; && substr_count($line, "\t") == 6) {  
        $tokens = explode("\t", $line);  
        $tokens = array_map(&#39;trim&#39;, $tokens);  
        $tokens[4] = date(&#39;Y-m-d h:i:s&#39;, $tokens[4]);  
        $trows .= &#39;<tr><td>&#39; . implode(&#39;</td><td>&#39;, $tokens) . &#39;</td></tr>&#39; . PHP_EOL;  
    }  
}  
echo &#39;<table>&#39;.PHP_EOL.&#39;<tbody>&#39;.PHP_EOL.$trows.&#39;</tbody>&#39;.PHP_EOL.&#39;</table>&#39;;  
?>
Copy after login

运行之后就如下图所示,已经被写入到table当中

大功告成,如果只读取其中字段可自行修改即可。
